What is the best Credit Card for GRAB Pay Top-Up?

Amex True Cashback card is the only card left known to work. There may be other cards that work for now, but the recent Visa MCC change has nerfed most of them.

HAHA, I think most if not all credit cards have that in their exclusion list already, even UOB One Card excludes Grabpay top-up already.

I would think you're much better off just paying directly with a credit card that has like 2/3% cashback. Grab points work out to only be about 0.08% rebate.
